9 Reasons Why Cell Phone Signals Suddenly Go Bad

reasons why you have bad cell phone signal

What Causes Bad Cell Phone Signal?

You’re sitting on your living room couch, walking in your neighborhood, or sitting in your car waiting for your kids to get out of school. You’re texting or chatting on your mobile phone, when suddenly your call drops off or your conversation disappears.

Poor signal again? You're not alone. Nearly 75% of Americans occasionally drop calls and suffer from slow download speeds. The question is, why are you always getting weak signal and low bars?

See complete cell phone booster kits for your situation:

You think to yourself, “I’ve got to change carriers.” Not so fast! Chances are your carrier is not at fault (well, not always).

1. Heavy Cellular Traffic

Take a look at all the other parents sitting in their cars in front of the school, or all those other people caught in rush hour traffic. Chances are, most if not all are doing the same thing you are: texting or talking on their phones.

All those signals are fighting for space on the nearest cell phone tower. Once your phone has linked to a tower, you are unlikely to lose your call, but the more phone traffic that fights for a spot, the weaker your signal can become.

If your call is transferred to a tower that’s already full, your call could be dropped.

2. Building Materials: What Building Materials Block Cell Phone Signal?

The building material of your house, car, place of work, or run-of-the-mill shopping mall is the number one culprit for weaker signal in America. Metal and new-fangled tinted, low-E glass are the two materials most responsible.

If you routinely notice service fading in and out as you walk around your home, or if your signal improves when you stand near a window or door, it’s likely your signal is being blocked by metal construction material.

Read more on the materials responsible here.

3. Low Battery: Does Low or Faulty Cell Battery Affect Cell Reception?

If you’ve been putting off charging your phone battery, you may find yourself with a weak signal when you need it most. Your phone needs energy to maintain a connection with a cell tower, and it may struggle when its battery is low.

4. Does Weather Affect Cell Service?

Cell phones transmit and receive electromagnetic waves, which can be affected directly by weather phenomenon such as humidity, heavy cloud cover, thunder, lightning, wind, rain, snow and ice.

5. Blocking Your Own Antenna

Close your eyes and picture the early days of mobile phones. Sure, they were as big as shoe boxes, but they also had exterior antennas. The phones were heavy and unwieldy, but their signal was pretty consistent. That’s partly because of those exterior antennas. Today’s phones have antennas embedded inside the phone. If you’re not careful how you’re holding the phone, you can block the antenna, and lose your signal. Where exactly your embedded antenna is depends on you phone model, but a little bit of searching, and you should be able to find it. Now that you know where it is, you should have no trouble avoiding this issue.

6. Mother Nature: Do Trees Affect Cell Phone Reception?

Did you just walk into a grove of trees? The leaf canopy can block some cell signals and cause your call to fade or drop altogether. If your home is surrounded by large, coniferous trees, these can be causing a massive drop in your cellular reception.

You might also wonder if snow affects cell phone reception - it can. Just like other weather, snow can adversely affect cell coverage.

7. Hills and Valleys: Why is Cell Service Bad on Hills and Valleys?

Geographic features are a common reason for cell signal obstruction. If you live on one side of a mountain, and the only cell tower in your area is on the other, you’re not likely to get good reception.

8. Cosmic Events: Solar Flares and Cell Service

Eruptions on the surface of the sun send plumes of gas into the atmosphere, and have been known to disrupt mobile phone communications. These so-called solar flares produce shock waves that travel through space.

They can disrupt the signals sent to and from a satellite, and produce changes in the Earth’s magnetic field. Obviously, this does not bode well for your cellular signal.

9. Cell Tower Distance

This is a no-brainer. The farther away you are from a cell tower, the weaker the signal gets, which leads to the "fish tank" voice and the constant say-and-repeat moments. Oh, and the dreaded one bar of service.

Miscellaneous Concerns

Can a Cell Phone Case affect Signal?

It can, but only if you've got a real thick one, or one badly designed enough to fit over the location of your antenna. It can also cover your antenna if you have a case designed for a different smartphone model.

Do Magnets Affect Signal?

Electromagnetic fields can cause signal interference, but unless you're walking around with a magnet in your pocket, you're not likely experiencing much of that.

Does Weak Signal Drain My Battery?

Yes - your phone has to work significantly harder to communicate to and from your cell tower with weaker signal, resulting in significantly shorter battery life.

Dead Spots

Certain areas are just not covered by specific service providers. These are called dead spots, or dead zones.

To find out if you live or spend a lot of time in one of these dead spots, simply put in your address or zip code for your carrier:

  • Can search for domestic or international coverage.
  • Zoom up to sixteen times magnification.
  • Map data can be filtered by voice, data, or prepaid coverage.
  • Locations are searchable by address, postal code, country, or landmark.
  • Locations are searchable by address, city, or postal code.
  • Has interactive map
  • Zoom up to six times magnification
  • Can show region and route data for up to five addresses.
  • Zoom up to eleven times magnification.
  • Locations are searchable by address.
  • Data can be filtered by voice or data coverage.
  • Zoom up to twelve times magnification.
  • Locations are searchable by address.

These dead zones occur whenever there is any kind of obstruction between the user and the cell phone tower or a lack of towers in general.

How Can I Boost My Poor Cell Phone Signal?

A cell phone signal booster increases your weak signal up to 32 times, whether at home, in your car, or in a public place such as an office building.

It works by pulling in weak signal, amplifying it multiple times, then rebroadcasts the boosted signal to an area in need.

The results? Improved carrier service. Faster internet. Better talk & text.

Here are all the features and benefits of using a cell phone booster:

  • Works for all cell phones & cellular devices.
  • Carrier-proof: Works for all carriers in USA & Canada.
  • One-time purchase, no monthly fees.
  • No need for WiFi or any broadband connection.

Below are the top signal booster models for increasing your phone's signal and service at home, your office, or your vehicle.

How to Fix Bad Cell Phone Reception at Home

The Best Cell Phone Signal Booster for Home

  • Up to 5,000 sq. ft. of coverage under best conditions
  • Up to +65 dB of gain, with 21 dBm uplink and 12 dBm downlink
  • Multiple accessories for maximum coverage and customization (sold separately)
  • Complete coverage for multiple rooms or midsize home for all carriers across multiple devices
  • Outdoor yagi antenna and indoor panel antenna configuration, with stylish fabric front

The weBoost Home MultiRoom is designed to cover several rooms, an entire floor, or a whole midsize, one-story home with boosted cellular signal. It bypasses most of the reasons cell phone signals go bad by bringing the existing outdoor signal inside via antennas and cables, boosting the signal, and rebroadcasting it within a defined space.

As its name suggests, you can expect multiple rooms of coverage with the unit assuming decent outside signal. With flawless outside signal, you can expect up to 5,000 square feet of coverage, but in most situations you'll get around 2,000-3,000 square feet of indoor coverage. If you live in a rural area with very weak outdoor signal, expect significantly reduced coverage. In fact, if you’re in an area with next to no signal, this is the lowest grade home signal booster you should ever consider buying.

It features a nice, clean look, with a fabric indoor panel antenna that won't stand out amid your existing home decor.

The weBoost Home MultiRoom boosts signal for all major North American carriers. Should you ever change carrier, the weBoost Home MultiRoom will still work.

If you live in an extremely weak signal area, or have a really big house you want to cover, consider its sister product, the weBoost Home Complete.

  • Up to 7,500 sq. ft. of coverage under best conditions
  • Up to +72 dB of gain, with 24 dBm uplink and 12 dBm downlink
  • Multiple accessories for maximum coverage and customization (sold separately)
  • Complete coverage for entire home for all carriers across multiple devices
  • Outdoor yagi antenna and indoor panel antenna, with stylish fabric front

Our Review:

The weBoost Home Complete is absolutely the most powerful consumer line booster you can get. With an additional +5 dB over the Home MultiRoom, it's roughly a shade over 3x more powerful.

Best case scenarios can expect coverage up to 7,500 sq ft. More likely results can at least expect 4,000-5,000 sq ft even with below average outside signal. Again, fringe zones can expect a little less.

It features an aesthetically pleasing design to fit in with typical home decor.

If you have extremely poor signal (remote area) or need wide coverage for a building 5,000 sq ft and over, the weBoost Home Complete is your new best friend.

  • 1-2 room coverage:
    Improves 4G LTE & 3G coverage up to 1,500 sq ft.
  • High-powered range: Up to +60 dB gain for 32X stronger signal.

Our Review:

The weBoost Home 4G is a nice cheap option if you're on a budget and only need spot coverage.

Depending on the outside signal, you may get 1-2 room coverage under best conditions. But you're not here because of best conditions, so it's more realistic to say desktop to small room coverage (about 250 to 500 sq ft).

Most customers have told us they're much closer to the inside antenna than anticipated for better signal. Great option for single office, home office (SOHO) and small areas like cabins and apartments. Good starter kit if you have decent outside signal but doesn't cover the whole home and not a strong performer in rural areas with poor signal.

The best Cell Phone Signal Booster for Car

  • Up to +50 dB of gain - the max allowed for a mobile signal booster in North America
  • Highest uplink output of any vehicle booster
  • Works for all phones and all carriers
  • Boosts 698-716 MHz, 729-746 MHz, 777-787 MHz, 824-894 MHz, 1850-1995 MHz, 1710-1755/2110-2115 MHz cellular radio frequencies.
  • Sleek, metallic exterior designed to displace excess heat for peak performance
  • Custom bracket for under seat or in-truck mounting options
  • Easy to use SMB connectors
  • Better talk, text, and data speeds guaranteed

The weBoost Drive Reach is the newest, most powerful vehicle booster from Wilson Electronics.

A slim outside antenna picks up signal. An indiscreet inside antenna (usually Velcroed to the driver seat) broadcasts signal inside. You have to be about an arm's length to get the boosted signal, so it's best for your typical sedan, truck, or SUV.

This is the best booster no matter where you live, as not only does it reach farther to the cell towers for rural areas, but it does a better job handling more noisy, urban environments than other signal boosters on the market. Highly recommended.

Cradle Solution

  • Boosts Voice, Text Messages, and Data
  • For a single smartphone
  • Up to +23 dB Gain

Our Review:

The weBoost Drive Sleek is about price and performance for the single user.

It uses a magnetic vent mount and when paired with a bluetooth headset, it really shines for regular talk & text and hands-free navigation.

Your smartphone has to be in the cradle to get maximum signal boost. New design allows for wider smartphones and small tablets.
